The lentiviral vector used is a self-inactivating (SIN) vector in which the viral enhancer and promoter has been deleted. Transcription inactivation of the LTR in the SIN provirus increases biosafety by preventing mobilization by replication competent viruses and enables regulated expression of the genes from the internal promoters without cis-acting effects of the LTR (Miyoshi et al., J Virol. 1998).

Mycoplasma Testing: The A375-hNIS-Puro cell line has been tested for mycoplasma contamination and is certified mycoplasma free.

In vitro: This is a high hNIS expressing cell line suitable for use as a positive control cell line in iodine uptake assays to verify NIS expression.

In vivo: A375 cells form tumors post implantation into immunosuppressed mice. The in vivo growth of these tumors can be monitored using noninvasive, high-resolution 3D PET/SPECT imaging.

NIS Functional Assay (Iodine Uptake): Cells were incubated with 125I for 1h in the presence or absence of KClO4, an inhibitor of NIS-mediated iodine uptake. Radioiodine concentrated within the cells was measured with a gamma counter.
